A simple strategy to prepare AIE polymers is invented using an AIE initiator for atom transfer radical polymerization. The dual photoresponse by intramolecular charge-transfer and luminogen aggregation of the initiator is well-realized and even enlarged after polymerization, due to the linkage of polymer chains.

Memory devices based on 4N4OPz exhibit excellent ternary memory behavior with high ON2/ON1/OFF current ratios and low switching threshold voltage.

Three novel bis(amidate) rare-earth metal amides were prepared and characterized. Treatment of CO2 with terminal alkynes obtained propiolic acids in high to excellent yields using the highest reactive Nd-based catalyst at ambient pressure.
